I can agree with more flare but not more theory crafting. If anything, VT 2 had more builds floating around than Darktide. Some were quite silly. I remember the Bulwark Kruber build… Lots of stamina plus a shield
Compare that to Darktide… The last few times I looked up a guide, it was almost always crit strike and damage with some flares as you mentioned
Let us say in theory I am wrong. Then I would say that expanding the passive trees may help encourage theory crafting if the crafting system was improved along side it. I was responding to a post on that matter. That can be found here
If say Veteran had a tree specific to heavy weapons, specific to a Bolter, etc… Then that may open new doors
